"The general Tiéfo territory lies to the south of Bobo-Dioulasso in the provinces of Comoé and Houet. There are Tiéfo villages located in the departments of Tiéfora and Sidéradougou in the Comoé province and in the departments of Bobo-Dioulasso, Péni, and Karankasso-Vigué in the Houet province. According to Kerstin Winkelmann, the following villages are ethnically Tiéfo: Dramandougou, Nyafogo, Koumandara, Dégué-Dégué, Derege, Laranfiera, Mousoubadougou, Yegere, Dabokeri, Noumouso, Tanga, Yanga, Kiefandougou, Dandougou, Kadio, Farajan, Sourkoutomo, Me, Matourkou, Damogan, Tien, and Kodala (Winkelmann 1996:165). All together, this area of about 20 small villages covers approximately 1,500 km2. The only known village where Tiéfo is presently spoken is Dramandougou Tiéfo, a village located in the department of Tiéfora in the province of Comoé. Winkelmann also notes that certain older people of Nyafogo and Noumoudara still know some of their language (Winkelmann 1996:166)."
